A researcher wants to determine if the exam scores of the students are dependent on the length of time spent in studying the subject. Ten students in a certain class were taken and the results are shown in the table below where X is the time spent in studying the subject in hours and Y is the examination scores. X (time)Y (score) 1.580 3.083 1.2583 0.570 3.585 2.575 1.070 3.090 2.586 4.091 Determine the simple linear regression equation Y = a + bX. (round off values up to 1 decimal place)
